MEANS FOR REMOVING CARBON FROM ENGINE-CYLINDERS.

' in the art to which it appertains to make and use the same.

The invention relates to means for re- -moving carbon from engine cylinders.

. manner and at the same time obviating any possibility of soiling the clothing or hands of such person.

A further object of the invention is to provide a means for removing carbon from engine cylinders of varying types such as gas or other engines without requiring the removal of the piston therefrom and also without the necessity of any' labor on the part of a person as one cylinder of the engine may be cleaned while the other cylinder is being operated. I

With these and other objects in view the herein described means employed in carrye ing out the same is accomplished by the steps and in the manner as will be hereinafter more fully described in detail, and illustrated in the accompanying drawings, while the novelty of the invention will be pointed out in the claims hereunto appended.

In the drawings :--Figure 1 is a frag- .mentary sectional view of a gas engine and its piston with the means for cleaning the carbon from the cylinder shown in position therein. Fig. 2 is a detail plan view of the means employed for cleaning the carbon from the engine cylinder, the said means being shown on an enlarged scale. Fig. 3

; is a side elevation of a tool for removing the said means from the engine cylinder.

Similar reference characters indicate corresponding parts throughout thev several views in the drawings.

Referring to the drawings by numerals 5 designates generally the cylinder of a gas engine which is of the ordinary type shown in vertical position the same being provided with a threaded opening in its head to detachably' receive the usual spark plug 6 for igniting the compressed gases on the compression stroke of the piston 7 working within said cylinder. This type of cylinder is merely shown for the sake of illustrating the manner of use of the means for removing the carbon accumulated therein as will be hereinafter more fully described and also the method and manner in carrying the said means into operation.

The means above mentioned comprises a chain of loosely joined coiled rings 8 each ring being formed of a single strand of wire bent to provide a series of convolutions 9 the same being arranged in juxtaposition and of corresponding diameter to each other. The single'st-rand of wire is of the same cross sectional area throughout its entire lengtlrand by the arrangeme'nt of the convolutions in juxtaposition to each other one strand from the wire will lie close to and upon-the adjacent coil and said rings are connected by passing the coils of one ring between one free end of one convolution and the adjacent convolution of another ring and then by twisting the latter ring it will link with the said other ring after the latter has passed the remaining free end of the second named ring. The chain of loosely connected rings 8 may be varied either by increasing or decreasing the same as the occasion may require.

Connected to the outer rings 8 of the chain are arcuate shaped terminal members 10 each being formed of a single strand of wire helically wound, the same being separated from each other a desirable distance the scraping action of the member. Furthermore, by virtue of these terminal members, the chain will be prevented from mov ing underneath the valves, since each valve lifts approximately a quarter of an inch and the, diameter of each terminal member is considerably greater than a quarter of an inch, so that should a terminal member move to a position in registration with the valve, the latter will shove the member back from the port, and thus the proper working of the valve is not interfered with during removal of the carbon from the cylinder. It will be noted also that the terminal members are loosely mounted on the terminal rings of the chain and are free to move in either direction on said rings, the value of this being that the terminal members may act as hammers when in motion to knock scale and the like from the cylinder wall.

The mode or method of carrying the above means into operation consists in removing the spark plug 6 from one cylinder 5 of an engine of the twin cylinder type or multiplied cylinders whereupon the chain is introduced through the spark plug opening in said cylinder 5 into its explosive chamber and thereafter about 5'; pint of kerosene oil is poured into the cylinder through the spark plug opening and then the said spark plug is replaced in the opening in the cylinder head. Now the ignition circuit of the cylinder is out OK whereupon the engine is started by running the same with the remaining cylinder or cylinders for a few minutes, so that the piston 7 will reciprocate within the cylinder moving with it the chain which will remove all carbon accumulated within the explosion chamber of the cylinder. After the explosion chamber has been cleaned in this manner the spark plug 6 is again removed from its opening in the cylinder head and by the employment of a hook member 11 which is of the required length is inserted through the spark plug opening in the head of the cylinder 5 and engaged with the chain so that it may be readily and quickly removed from the said cylinder. The remaining cylinder or cylinders of the engine are cleaned and the removal of carbon from the explosion chamber or chambers thereof is accompanied by repeating the foregoing procedure in the mode and manner set forth.

What is claimed is 1- 1. A cleaner comprising a chain, and arcuate helical wire elements loosely mounted on the terminal links of the chain and adapted to slide in either direction on said links.

2. A cleaner comprising a chain having a plurality of rings,loosely connected to each other, each ring being formed of a single strand of wire bent to provide a series of convolutions, and arcuate helical wire elements loosely mounted on the terminal rings of the chain and adapted to slide in either direction on said terminal links.

In testimony whereof, I aflix my signature, in presence of two witnesses.
